Ridges and Hips

Compactroll is laid on top of the roof, ensuring air ventilation and weatherproofing
Available in rolls, it is easy to manipulate and bring on top of the roofs
The aesthetic added-value of Compactroll is obvious compared to mortar solutions


Ridges and hips are the location of the roof where maximum heat is concentrated, below the tiles. It is very important to exhaust this heat in order to have a comfortable roof. In addition, it is also important to have a waterproofing system to avoid the risk of leaks. To tackle this issue and avoid the accumulation of un-aesthetic mortar on the roof, MONIER has developed COMPACTROLL®

Compactroll is a new and universal solution for dry ridge and hip fixing. Essential components of Compactroll are the flexible side parts. The integrated metal grid and special adhesive strips allow easy and long lasting attachment to plain and profiled roofing materials.
With integrated stretch parts on both sides, Compactroll can also be used on bolder profiled roof tiles such as the Elabana. The mid-section is made of water-repellent fleece with very high ventilation value.

Ridges are the areas with the highest concentration of heat. It is critical to lay Compactroll correctly, providing a support via a ridge tree and ridge runner, to ensure a correct aeration and watertighness.

The laying of the cap ridges is also important. It should take into account the usual wind direction and in case Compactroll is not used, mortar can be put in order to avoid un-aesthetic finishing (see pictures)

Specific fittings have been deisgned to finish correctly the roof top lines and must be used according to the design of the roof.

Clips are mandatory to maintain the ridges together

Hips are difficult areas with cut tiles and slopes. It must be correctly laid to avoid any risk of leakages. 

In addition, due to the slope, cap ridges may fall down, it is critical to fix them and use our ridge clips to maintain them together.
